The Hawker 400XP is a light jet, which was developed and built by Mitsubishi Heavy Industries as the MU-300 ‘Diamond’.

In 1985, Mitsubishi sold the design and production rights to Beechcraft who initially manufactured the aircraft under their own designation, the Beechjet 400. Following design revisions and a buyout of the Hawker series of business jets in 1993, the Beechjet 400 went on to become the Hawker 400XP.

Since its first flight as the MU-300 in 1978, nearly 1,000 aircraft have been delivered globally.

Alongside the Hawker 400XP, the Beechjet 400 was also developed for service in a variety of roles such as the T-1 Jayhawk military training variant for the United States Air Force and the T-400 variant for the Japan Air Self-Defense Force, proving testament to the design’s exceptional performance and capabilities.
